Course detail

General Biophysics

FEKT-BPC-OBFAcad. year: 2024/2025

General biophysics covers the main study areas of general as well as medical biophysics, namely biophysics of membranes, senses, the cardiovascular and respiratory system, laboratory and clinical optical methods, hazards and biophysical interactions of some instrumentation methods including elements of radiobiology. Practical exercises and demonstrations to show the students how to measure non-electric parameters of living organisms, that correspond to the theoretical lessons.

Department

Faculty of Medicine, Masaryk University Brno (LF MU)

Entry knowledge

Requires knowledge of the physical fields, i.e. knowledge gained in courses Physics I and Physics II. Furthermore, knowledge of general physical chemistry, i.e. knowledge in biochemistry.

Rules for evaluation and completion of the course

Exam consists of a test and an oral part. More than 14 points out of 25 possible is a requirement for passing the test, oral and overall result is evaluated according to the classification practices LF MU. Exam aims to test knowledge from the the membrane, cell and organ biophysics and also tests knowledge of the impact of physical fields on the human body.
Laboratory exercises are compulsory (absence must be replaced after consultation with the teacher), attendance at lectures is optional.

Aims

To offer a review of the main issues of general and medical biophysics with focus on the physiological biophysics and the impact of physical factors on living organisms.
The student is able to describe and explain the principle of the influence of physical fields on the human body - at the cellular and organ level. Furthermore, he gains the knowledge from the selected parts of Molecular and Medical Biophysics as specified in the "Outline". In practical exercises, he gains related skills of spectrophotometry, refractometry, polarimetry, conductometry, measuring liquid viscosity, temperature or absorption of ionizing radiation.
